Needles Blue Agate

We were introduced a few years ago to "Needles Blue Agate" by Maggie McShan from Needles, California. Maggie and her husband Frank ran an Old Time Rock Shop there in Needles and are well known in the Rockhound community. Chris obtained a very interesting Needles Blue Agate specimen display box (NOT FOR SALE) that Maggie and Frank have marked from the Blue Danube Mine.

We'll let the McShans explain this mineral with the description in their display. This mineral is very rare and only found in one location. The agate forms in layers within the matrix stone and must be cut out to make cabochons or other jewelry. We have been looking for Needles blue Agate for years now and finally found some old stock that probably came from Maggie and Franks shop. When Maggie died the entire shop sold off with little or no notice to the rockhound community so many years of collections were lost to who knows where. From time to time we find a few pieces from their collections.

Amphiboles crystallize into two crystal systems, monoclinic and orthorhombic. Amphiboles are minerals of either igneous or metamorphic origin; in the former case occurring as constituents (hornblende) of igneous rocks, such as granite, diorite, andesite and others. Those of metamorphic origin include examples such as those developed in limestones by contact metamorphism (tremolite) and those formed by the alteration of other ferromagnesian minerals (hornblende). Pseudomorphs of amphibole after pyroxene are known as uralite.

The name amphibole (from the Greek word amphibolos meaning 'ambiguous') was used by René Just Haüy to include tremolite, actinolite, tourmaline and hornblende. The group was so named by Haüy in allusion to the protean variety, in composition and appearance, assumed by its minerals. This term has since been applied to the whole group. Four of the amphibole minerals are among the minerals commonly called asbestos. These are: Anthophyllite, Riebeckite, Cummingtonite/Grunerite series, and Actinolite/Tremolite series. The Cummingtonite/Grunerite series is often termed Amosite,or Brown Asbestos and Riebeckite is known as Crocidolite or Blue Asbestos. These are generally called Amphibole Asbestos.
